github okonet / lint-staged / test / resolveTaskFn-chunked.spec.js View on Github external
it('should respect chunk size and concurrency', async () => {
      expect.assertions(6)

      const taskFn = resolveTaskFn({
        ...defaultOpts,
        pathsToLint: ['test1.js', 'test2.js'],
        subTaskConcurrency: 2
      })
      await taskFn()
      const [[chunks, mapper]] = pMap.mock.calls
      expect(mapper).toBeInstanceOf(Function)
      expect(pMap).toHaveBeenCalledWith([['test1.js'], ['test2.js']], mapper, { concurrency: 2 })

      // Check that calling the mapper invokes execa
      const [c1, c2] = chunks
      await mapper(c1)
      expect(execa).toHaveBeenCalledTimes(1)
      expect(execa).lastCalledWith('test', ['test1.js'], { reject: false })
